The company, capable of finding problems with the MOULD FLOW before mould opening, pays attention to the problems during design and production, and provides solutions to reduce risks, shorten the construction period and improve quality. (For details, see mould flow analysis cases)

During filling of hot runner with six valve gates, we can see stagnation occurs in the very center of the upper part and welding marks appear on the main surface.

Open the first gate and then the second and third gates when the melting flow arrives at each of them. In this mode, the top will be filled earlier than the bottom.

Although the mould flow is uneven in the runners, we can reduce the impact arising from the uneven flow by controlling the gates. In addition, four gates on the top can reduce the production of miniature.

Most of the welding marks will appear inside the grids but not on the main surface.
